Hello @diablo24. They "Local LAN" rule is a pre-defined rule that is used for Wireless Firewalls, for all Internal (Private RFC addresses). You won't be able to use "Local LAN" as a keyword in your firewall rules.
The only other Keywords I'm aware of is "ANY" for any and the ability to use "-" in-between port numbers, for example, 1-5000 would imply port numbers 1 to 500.
This document may also help understand the Firewalling rules construct in more detail - https://documentation.meraki.com/MR/Firewall_and_Traffic_Shaping/Firewall_Rules
